You haven't said anything about the process you used, so it's hard to
say what you've overlooked.
The basics thing to remember is that the chroot is expected to be a
complete system. If you need name resolution, then /etc/passwd and
/etc/group need to be present in the chroot. If you need DNS
resolution, /etc/resolv.conf, too. If your system uses sssd, chroot
won't have access to it. The shell and all of the commands and all of
the associated libraries must be in the chroot. Finally, the user's
home directory has to exist within and relative to the chroot directory.
So, if the user's home directory is /home/user and you want to chroot
them there, you would expect to have something like:
/home/user/bin/bash
/home/user/etc/bash_profile
/home/user/home/user/.bash_profile
You could symlink /home/user/home/user to /, as well.
